<p>To get the current date and time, just call <code>moment()</code> with no parameters.</p>
<pre><code class="language-javascript">var now = moment();
</code></pre>
<p>This is essentially the same as calling <code>moment(new Date())</code>.</p>
<p><strong>Note:</strong> From version <strong>2.14.0</strong>, <code>moment([])</code> and <code>moment({})</code> also return
now. They used to default to start-of-today before 2.14.0, but that was
arbitrary so it was changed.</p>
<p><strong>Note:</strong> Function parameters default to <code>undefined</code> when not passed in. Moment treats <code>moment(undefined)</code> as <code>moment()</code>.</p>
<pre><code class="language-javascript">var x = undefined;
moment(x).isSame(moment(), &apos;second&apos;); // true
